FLASH MODE: TTL AUTOFLASH This flash has three flash modes: TTL, Manual (M), and Multi (Stroboscopic). In TTL mode, the camera and the flash will work together to calculate the correct exposure for the subject and the background. In this mode, multiple TTL functions are available: FEC, HSS, second curtain sync, etc. Press Mode Selection Button and three flash modes will display on the LCD panel one by one with each pressing. TTL MODE Press Mode Selection Button to enter TTL mode.
• When the shutter button is fully pressed, the flash will fire a preflash that the camera will use to calculate exposure and flash output the instant before the photo is taken. Display “Hi”: When the flash output value is up to the maximum value, “Hi” will be displayed and blinking for 3 seconds. Adjust the camera’s parameters if underexposure appears. Display “Lo”: When the flash output value is up to the minimum value, “Lo” will be displayed and blinking for 3 seconds.
Setting FEC: ZOOM MODE ZOOM SYNC SLAVE SYNC SLAVE SET MODE ZOOM SYNC SET SET • Press the SET Button and the flash exposure compensation amount will be highlighted on the LCD panel. • Turn the Select Dial to set the amount. - “0.3” means 1/3 step, “0.7” means 2/3 step. - To cancel the flash exposure compensation, set the amount to “+0”. • Press button again to confirm the setting.
HIGH-SPEED SYNC High Speed Sync (FP flash) enables the flash to synchronize with all camera shutter speeds. This is convenient when you want to use aperture priority for fill-flash portraits. Choose the < > button: Press the button to turn on high-speed sync function. • With high-speed sync, the faster the shutter speed, the shorter the effective flash range. • Multi flash mode cannot be set in high-speed sync mode.
SECOND-CURTAIN SYNC With a slow shutter speed, you can create a light train following the subject. The flash fires right before the shutter closes. • Press the button then the < > icon displayed on the panel. The Second-Curtain Sync does not function in the wireless mode or the Multi mode.
FLASH MODE: MANUAL FLASH The flash output is adjustable from 1/1 full power to 1/128th power in 1/3rd stop increments. To obtain a correct flash exposure, use a hand-held flash meter to determine the required flash output. MODE MODE ZOOM SYNC ZOOM SYNC SLAVE SLAVE SET SET • Press button so that is displayed. • Turn the Select Dial to choose a desired flash output amount.
In high-speed sync mode, the adjustable flash range is 1/16~1/1. Flash Output Range The following table makes it easier to see how the stop changes in terms of f/stop when you increase or decrease the flash output. For example, when you decrease the flash output to 1/2, 1/2-0.3, or 1/2-0.7, and then increase the flash output to more than 1/2, 1/2+0.3, 1/2+0.7, and 1/1 will be displayed. Figures displayed when reducing flash output level 1/1 1/1-0.3 1/1-0.7 1/2+0.7 1/2+0.3 1/2 1/2-0.3 1/2-0.7 1/4-0.
In the M mode, achieved. high-speed sync and second curtain sync functions can be • Optical S1 Secondary Unit Setting In M manual flash mode, press the button so that this flash can function as an optic S1 secondary flash with optic sensor. With this function, the flash will fire synchronously when the main flash fires, the same effect as that by the use of radio triggers. This helps create multiple lighting effects.
• S1 and S2 optic triggering and off camera high-speed mode are only available in M manual flash mode. MULTI STROBOSCOPIC FLASH With stroboscopic flash mode, a rapid series of flashes is fired. It can be used to capture multiple images of a moving subject in a single photograph. You can set the firing frequency (number of flashes per sec. expressed as Hz), the number of flashes, and the flash output.
MODE MODE MODE ZOOM SYNC ZOOM SLAVE SYNC SLAVE ZOOM SYNC SET MODE SLAVE ZOOM SYNC SLAVE SET SET SET • Long press the button for 2 seconds so that is displayed. • Turn the Select Dial to choose a desired flash output. • Set the flash frequency and flash times. - Press the SET Button to select the flash frequency. Turn the Select Dial to set the number. - Press the SET Button again to select the flash times. Turn the Select Dial to set the number.
Calculating the Shutter Speed During stroboscopic flash, the shutter remains open until the firing stops. Use the formula below to calculate the shutter speed and set it with the camera. Number of Flashes/Flash Frequency = Shutter Speed For example, if the number of flashes is 10 and the firing frequency is 5 Hz, the shutter speed should be at least 2 seconds. To avoid overheating and deteriorating the flash head, do not use stroboscopic flash more than 10 times in succession.
• Stroboscopic flash is most effective with a highly reflective subject against a dark background. • Using a tripod and a remote control is recommended. • Stroboscopic flash can be used with “bulb mode”. • If the number of flashes is displayed as “--”, the firing will continue until the shutter closes or the battery is exhausted. The number of flashes will be limited as shown by the following table.
Maximum Stroboscopic Flashes: Flash HZ Output 28 1 2 3 4 5 6-7 8-9 10-19 20-50 60-90 1/4 6 3 2 2 2 2 2 2 2 2 1/8 14 14 6 4 3 3 3 2 2 2 1/16 30 30 30 20 10 8 5 3 3 3 1/32 60 60 60 50 50 40 12 5 5 5 1/64 90 90 90 80 80 70 60 20 10 10 1/128 90 90 90 90 90 90 80 70 30 20
WIRELESS FLASH SHOOTING: RADIO (2.4G) TRANSMISSION • You can set up three slave groups for TTL autoflash shooting. With TTL autoflash, you can easily create various lighting effects. • Any flash settings for the slave units on the master flash in TTL mode will be automatically sent to the slave units. So the only thing you need to do is to set the master unit for each slave group. There is no need to operate the actual slave units at all during the shooting.
• Even with multiple slave units, the master unit can control all of them via wireless. • In this user manual, “master unit” refers to the camera flash on a camera and “slave unit” will be controlled by the master unit. 1.
